Javascript TypeError:无法读取属性'；id'；试图制造不和时的未定义

我试图创建一个简单的discord bot，但是每当我运行

-setcaps

命令时，我会得到：

TypeError:无法读取未定义的属性“id”

我不确定是什么原因造成的。如果你能提供任何帮助，我将不胜感激。我不确定要添加什么来提供更多细节，我正在使用node.js的最新稳定版本并使用notpad进行编辑++

let firstsinded=message.sindements.users.first（）；
defineduser=第一个提到的.id；

//最后，运行这个..记住如果你使用的是帮会唯一的方法，请确保在末尾添加帮会ID，
economy.updateBalance（defineduser+message.guild.id，parseInt（args[0]））。然后（（i）=>{//并确保始终将要添加的数字解析为整数
message.channel.send（`**用户定义的帐户中添加/减去了${args[0]}.*`）
});
}
//余额与货币
如果（msg==`${prefix}BALANCE`| | msg===`${prefix}MONEY`）{//如果消息是~BALANCE或~MONEY，则将运行此操作
//附加提示：如果你想让价值观变得独一无二，只要在你请求时添加+message.guild.id即可。
economy.fetchBalance（message.author.id+message.guild.id）。然后（（i）=>{//economy.fetchBalance获取用户id，找到它，并将数据与它一起放入i。
//让我们为此使用一个嵌入
const embed=new Discord.RichEmbed（）
.setDescription（`**${message.guild.name}隐藏**`）
.setColor（0xff9900）//如果在十六进制颜色之前加上0x，则可以设置任何十六进制颜色。
.addField（'Stash Owner'，message.author.username，true）//true使嵌入内联。Account Holder是标题，message.author是值
.addField（'Stash Contents'，i.money，true）
//现在我们需要发送消息
message.channel.send（{embed}）
